A global study involving 28,000-plus people offers the strongest evidence to date that lowering high blood pressure in seniors can reduce the risk of dementia, researchers said Tuesday.

Without significant treatment breakthroughs for dementia, reducing the risk of developing the disease would be "a welcome step forward," Ruth Peters, associate professor at the University of New South Wales in Sydney, Australia, said in a news release.

"Our study provides the highest grade of available evidence to show that blood pressure lowering treatment over several years reduces the risk of dementia, and we did not see any evidence of harm," said Peters, who is program lead for dementia at The George Institute's Global Brain Health Initiative in Newtown, New South Wales, Australia.

What remains unknown is whether additional blood pressure lowering "in people who already have it well-controlled," or whether starting treatment earlier in life, would reduce the long-term risk of dementia, Peters said.

Isn't that already well established in the case of multi-infarct/vascular dementia?

Same comment just posted elsewhere.

TL;DR Put down the triple bacon cheeseburger and get the three bean chili sin queso instead.

Controlling current chronic medical conditions like hypertension and diabetes to prevent dementia has been the current recommendation from neurologists and family practitioners for a while now.

My dad had chronically high blood pressure and died of dementia. But he also had heart attacks and stents and vascular problems.

Don't abuse toxic exogenous hormone modulators, exercise.

Is that one-size-fits-all shaming solution really adding anything helpful to the topic?

Exercise is important, there is no denying that, however, the effect on blood pressure is usually not clinically enough. Even in the study you cited the mean drop in systolic/diastolic was -4.8/-3.19, which is small. The study in this post uses a criteria of -10/-5 to barely squeak out statistically significant results and demonstrate a negative correlation with dementia. Furthermore, according to the CDC about half of those with uncontrolled hypertension are at 140/90. Exercise is often inadequate to control hypertension and medications are necessary limit morbidity.
